title: Clinical and angiographic findings in black patients with suspected coronary artery disease.
abstract: To determine the clinical variables and coronary angiographic findings in black patients with suspected coronary artery disease, we analyzed the data on consecutive black patients undergoing their first coronary angiogram over a three year period at the Cook County Hospital, Chicago, Illinois. We compared these findings to those of black and white patients from previous studies. There were 654 patients with a mean age+/-standard deviation of 56+/-10 years; 309 (47%) were men. Two hundred nineteen patients (33%) presented with unstable angina, 75 patients (12%) with acute myocardial infarction and 338 patients (52%) with chronic stable angina. Three hundred forty-six patients (53%) had 50% or greater stenosis in at least one of the major vessels. Among the patients with coronary artery disease, 128 patients (37%) had one vessel disease, 102 patients (29%) had two-vessel disease, and 116 patients (34%) had three-vessel disease. Black patients who undergo coronary angiography for suspected coronary artery disease have a high frequency of normal coronary angiogram or non-obstructive coronary artery disease. The frequency of 1-, 2- and 3-vessel disease in blacks with coronary artery disease is comparable to those observed in whites in previous reports.
